Definitions
- the present invention relates to a scarifier for deep strip-tillage, that allows the soil to be in adequate conditions for planting or sowing after a single trip, and that operates with great energy efficiency, leading to an improved production environment.
- Soils with a history of sugarcane monoculture are often characterized as soils with low structure and high bulk density, resulting from a combination of soil working during the growing season and compaction caused by heavy and intensive traffic at the time of harvest.
- the present invention provides a scarifier for deep strip-tillage which also applies fertilizers for the production of industrial cultures.
- the scarifier for strip-tillage of the present invention clearly differs from inventions of the prior art, such as disclosed in U.S. Pat. No. 6,216,616 (Borgault) in that the incorporation of fertilizer is not done by means of coulter or disc furrow openers, and although there are active organs for soil cutting, technically they do not cause disruption of the soil. Moreover, disc furrow openers are not able to go deeper than 10 cm, and consequently the product application is relatively superficial.
- a scarifier for deep strip-tillage which comprises a plurality of tillage units a, spaced apart and located parallel to each other, where each tillage unit a comprises a support structure 2 over which corresponding tines 1 a , 1 b , 1 c are mounted, the lower ends of which are located at different heights, reaching deeper below the ground d toward the rear of the scarifier.
- each tillage unit a comprises four tines, the front tine 1 a and the rear tine 1 c being located in a centered position and intermediate tines 1 b , being located at each side of the unit a.
- the two intermediate tines 1 b are located at a same level relative to the ground.
- the scarifier comprises three tillage units a which are equally spaced apart on the width of the scarifier.
- the tillage units a are located on a general support structure, and are capable of moving transversally in order to modify the distance between them.
- each tillage unit a incorporates front cutting organs of the coulter or disk type 3 .
- the tines 1 a , 1 b , 1 c can move transversally over said support structure.
- each tillage unit of the scarifier for strip-tillage comprises four tillage organs makes it possible tilling in three depth ranges, unlike the mentioned subsoilers of the prior art which can only do it in two depth ranges.
- This constructive feature allows for a lower power requirement given the more gradual deepening of the elements. It also allows a greater working depth without causing adverse effects in the soil as a result of what is technically known as the critical depth.
- the tines arranged on the sides of the central action line are not paired or mated as in designs of other mentioned subsoilers, conferring a greater ability to work in soils with abundant living or dead vegetation cover without getting stuck.
- the arrangement of the front cutting organs of coulter or disk type also gives the scarifier for strip-tillage of the invention enhanced working capacity in areas with large volume of crop residues on the ground surface.
- the lower energy consumption is mainly given by the spatial arrangement of the tines and by the fact that it is a strip-tillage system acting only on the portion of soil that must be disrupt.
- the scarifier of the present invention comprises a plurality of tillage units acting on a strip of ground, remaining between two of such tillage units an area which is not tilled.
- Each of these tillage units comprises at least two vertical tillage organs or tines arranged in a manner so as to perform deep strip-tillage in a single trip while fertilizer is incorporated.
- the tillage unit comprises four tillage organs or tines arranged so that they act at increasing depths towards the rear of the unit. These tillage organs or tines are preceded by superficial coulters for cutting surface residues, coulters which are not involved in the disruption of the soil and that are located ahead of the tines.
- the scarifier performs the tillage at great depth in one trip and with lower energy demand, thanks to the tines or tillage organs acting on strips and successively at different depths.
- each tillage organ or tine there is a fertilizing system that simultaneously applies the product at different depths enabling application of large doses without the usual drawbacks of this approach.
- FIG. 1 is a side view of one of the tillage units used by the soil scarifier object of the present invention.
- FIG. 2 is a top or plan view of the tillage unit of FIG. 1 .
- FIG. 3 shows the soil scarifier of the present invention pulled by a tractor through its drawbar, and wherein it is displayed the spacing “c” between the tillage units in order to achieve strip-scarifying.
- FIG. 4 is a side view of the tillage unit of FIG. 1 , with a fertilization system applied on each tillage tine.
- FIGS. 1 and 2 show a preferred and nonexclusive embodiment of the present invention, where the scarifier for deep strip-tillage comprises a plurality of tillage units a, spaced apart and parallel to each other, and wherein each tillage unit a comprises a support structure 2 on which respective tines 1 a , 1 b , 1 c are mounted, the lower ends of which are located at different heights, with the depth below the ground d being greater toward the rear of the scarifier.
- the scarifier incorporates three front cutting organs of the coulter or disk type 3 , positioned in line with the tillage organs or tines 1 a , 1 b , 1 c.
- FIGS. 1 and 2 also show that each tillage unit a, has four tines 1 a , 1 b , and 1 c , the front tine 1 a and the rear tine 1 c being located in a centered position and intermediate tines 1 b , being located at each side of the unit; said two intermediate tines 1 b being located at a same level relative to the ground d.
- FIG. 2 also shows that the front tine 1 a and the rear tine 1 c are located in alignment, and the intermediate tines 1 b are located at a same lateral distance with respect to said front and rear tines 1 a and 1 c.
- the tines 1 a , 1 b , and 1 c can move transversally over said supporting structure, since they are mounted on a crossbar 4 .
- all tillage units a are equally spaced apart on the width of the scarifier at a distance c.
- Tillage units a are placed on a general support structure, and are able to move transversely to modify the spacing distance c between them.
- FIG. 4 shows a fertilization system incorporated to the tillage unit a, comprising a conduit 5 which receives fertilizer from a hopper 6 .
